The Crucial 10th anniversary kit found its limits on the 366MHz FSB as the 3x multiplier would have brought the memory up to 1100MHz. This frequency was not reachable, so a 2.5x multiplier had to be used resulting in a frequency of 915MHz. The Corsair Value Select memory was limited to a 2x multiplier which resulted in output of 6.6GB/s versus 7.2GB/s delivered by the Crucial kit.
